All-in-one solar charge inverter V1.0 53
10
PV reverse polarity
protection
When the PV polarity is reversed, the machine will not be damaged.
11
AC reverse
protection
Prevent battery inverter AC current from being reversely input to
Bypass.（In off-grid mode）
12
Bypass over current
protection
Built-in AC input overcurrent protection circuit breaker.
13
Battery input over
current protection
When the discharge output current of the battery is greater than the
maximum value and lasts for 1 minute, the AC input would switched
to load.
14
Battery input
protection
When the battery is reversely connected or the inverter is short-
circuited, the battery input fuse in the inverter will blow out to
prevent the battery from being damaged or causing a fire.
15
Charge short
protection
When the external battery port is short-circuited in the PV or AC
charging state, the inverter will protect and stop the output current.
16
CAN
communication
loss protection
In parallel operation, an alarm will be given when CAN communication
is lost.
17
Parallel connection
error protection
In parallel operation, the equipment will be protected when the parallel
line is lost.
18
Parallel battery
voltage difference
protection
In parallel operation, the equipment will be protected when the battery
connection is inconsistent and the battery voltage is greatly different
from that detected by the host.
19
Parallel AC voltage
difference
protection
In parallel operation, the equipment will be protected when the AC IN
input connection is inconsistent.
20
Parallel current
sharing fault
protection
In parallel operation, the running equipment will be protected when
the load difference of each inverter is large due to improper
connection of current sharing line or device damage.
21
Synchronization
signal fault
protection
The equipment will be protected when there is a fault in the guidance
signal between parallel buses, causing inconsistent behavior of each
inverter.
